| 摘 要： | 为掌握冷藏对石蒜(Lycoris radiata)鳞茎休眠生理及开花的影响,研究了石蒜球根在6和9℃低温下分别冷藏4、7、9周后,鳞茎尖内的生理变化,并观察其开花时间.结果表明:在6℃冷藏4周花期推迟19d;9℃冷藏4周花期推迟12d;6、9℃条件下冷藏7和9周均未开花.在6℃冷藏4周条件下,蛋白质和核酸质量分数均保持着较低的水平;同时对内源激素质量摩尔浓度测定表明内源激素IAA极显著对花期具有影响作用,ABA、ZR也具有影响花期的作用,而内源激素GA3质量摩尔浓度变化对开花无显著影响. |

| Abstract: | An experiment was conducted to study the physiological change and flowering time of Lycoris radiate bulbs after 4,7 and 9 weeks of storage at low temperatures of 6 degrees C and 9 degrees C in order to discuss the effects of cold storage on dormancy physiology and flowering regulation of L.radiate.Result showed that the flowering time postponed 19 days at 6 degrees C for 4 weeks,12 days at 9 degrees C for 4 weeks,but there were no flowers to be seen at 6 degrees C and 9 degrees C for 7 and 9 weeks,respectiv... |
